Given the rapidly declining state of the Ravens following consecutive losses, coach John Harbaugh delivered a stern message Monday.

The gist of it one day after a 19-16 loss to the Pittsburgh Steelers that included costly late special-teams breakdowns: Harbaugh's not going to tolerate substandard performances, and the team won't hesitate to make changes in an effort to upgrade the roster.

On Monday as the Ravens (3-4) enter their bye week, demoted veteran offensive Bryant McKinnie was traded to the Miami Dolphins in exchange for a conditional late-round draft pick. McKinnie had already been replaced by new left tackle Eugene Monroe.
